13.3 Plotting on the same axis

Example:

import backtrader as bt

cerebro = bt.Cerebro()

data0 = bt.feeds.MyFavouriteDataFeed(dataname='futurename')
cerebro.adddata(data0)

data1 = bt.feeds.MyFavouriteDataFeed(dataname='spotname')
data1.compensate(data0)  # let the system know ops on data1 affect data0
data1.plotinfo.plotmaster = data0
data1.plotinfo.sameaxis = True
cerebro.adddata(data1)

...

cerebro.run()

data1 gets some plotinfo values to:

• Plot on the same space as plotmaster which is data0

• Get the indication to use the sameaxis

The reason for this indication is that the platform cannot know in advance if the scales for each data will be compatible. That’s why it will plot them on independent scales
